nervous system phenotype ( J:99610 )
N
• generation and patterning of lateral ganglionic eminence (LGE) precursors is normal in mutants
abnormal neuronal migration ( J:99610 )
• early- and late-born neurons fail to migrate to appropriate positions to form ventral striatum
abnormal striatum morphology ( J:99610 )
• between E13 and 16, striatal mantle is more densely populated by proliferating precursors compared to wild-type
abnormal ventral striatum morphology ( J:99610 )
• migration or differentiation of ventral striatum (VS) neurons is disturbed in mutants
• at E13 to birth, the striatal bridges are absent
abnormal nucleus accumbens morphology ( J:99610 )
• staining for the markers Brn5 and Robo at E13 reveals a neural differentiation defect restricted in the region of the nucleus accumbens and olfactory tubercle (OT), and not the rest of the striatum
abnormal olfactory cortex morphology ( J:99610 )
• at E13 to birth, the striatal bridges and the olfactory tubercule (OT) layers are absent

abnormal neuronal migration ( J:99610 )
